1958. Geophysic Chronometer, model 2985

1958

Jaeger-LeCoultre Geophysic Chronometer was created in 1958 on the occasion of the Manufacture’s 125th anniversary. It was intended for the scientists of the International Geophysical Year, an unprecedented scientific operation. In the middle of the Cold War, several thousand researchers from 67 countries combined forces to lay the groundwork for sharing knowledge in the Earth sciences. They set up numerous bases in the Arctic. With its precision, toughness and resistance to magnetic fields, the Geophysic Chronometer accompanied their explorations. Along with the famous E168 model, the Artcurial sale will be offering an extremely rare version, which has not been seen at auction for over 10 years: the model 2985, dubbed Geophysic Luxe, of which only 103 were made. Its Jaeger-LeCoultre 478BWSbr calibre offers every technical device to guarantee the greatest accuracy: indirect central seconds, stop second, Glucydur balance wheel, swan-neck adjustment system (with regulator spring and setting screws), shock absorbers, precision end curves, anti-magnetic escapement, unbreakable spring, 17 jewels, an 18-carat yellow-gold case, silvered dial, appliqué hour-markers and gold hands.
